One advantage of the two bath pyro is the situation where you only have one roll of a rare or discontinued film so you cannot do the endless testing of every combination of time, temperature and dilution.
Both threads worked but the link to http://www.pyrocat-hd.com/html/TwoBathPyrocat.html lead to a hijacked page about software development. Also there seems to be several dilutions to choose from. I could use some clarity of this.
Gel filters are fragile compared to glass filters. I would not use one unless I had to and in over 60 years I have yet to find a filter that does not come in glass in the size I need.
My Nikon f/2.8 20mm to 35mm AF zoom lens has disappeared and I ended up replacing it with a Nikon f/2.8 20mm to 35mm AF-D zoom lens that cost less than the original all metal one I bought in 2005.

Nice infrared rendition as photographers have come to know it - and from a R25 filter, no less! Using an Orange filter, a common practice for landscape photographers...
Thank you!
The ISO 32 without filters is confusing.
Because f/5.6 @ 1/60 second is EV 11. Then uncorrect for the R25A filter is three steps, EV 11 12 13 14. And EV14 is f/16 @ 1/250 second for ISO 250.
So are my calculations wrong?
I have nine rolls of Konica Infrared 750 in the freezer. What is the ISO, not EI, before adjusting for the filter? I have several different filters I can use: R23, R35, R29 and R720, so I am looking for the manufacturer's ISO.
